The game is looking sweet. Great vegetation :)
One question - will the item line of sight be shown in a visual representation? like a brightened area where your character can see. Original Sin uses something similar, where only character visible items are highlighted, but it can make it really easy to miss things that might have been just on the edge of your vision range,

Free aim certainly appears to be more fluid, and it will also potentially work better in multiplayer environments, as multiple people trying to lock on to the same dead/dying target could be very frustrating.
